Electrical jack-plug

Abstract

An electrical jack-type connector, mainly for low voltage purposes, having a rod-shaped male part having terminals in the form of conducting, axially displaced contact rings, and a matching tubular female part having axially and peripherially displaced inner terminals to make contact with the contact rings of the male part, with the female part having an outer tube and an inner tube fitted therein, which inner tube is formed with rectangular slots for arrangement of the terminals of the female part, in each slot there being a flat substantially rectangular contact flap connected with a respective conductor located between the inner tube and outer tube in a narrow track extending on the tube wall parallel to the tube axis from the slot to an orifice at one end of the inner tube for connection with cable conductors within a closed end. The contact flaps are strip-formed rectangular pieces extending beyond the length of the slots so as to be forced to assume a curvature upon insertion of the inner tube into the outer tube.

I claim: 
     
       1. An electrical jack-type connector, mainly for low voltage purposes, comprising a rod-shaped male part (1) having terminals in the form of conducting, axially displaced contact rings (2) and a matching tubular female part (7) having axially and peripherally displaced inner teminals to form contact with the contact rings (2) of the male part, which female part (7) comprises an outer tube (9) and an inner tube (10) fitted therein, which is formed with slots for the arrangement of the terminals of the female part (7), each being in connection with a respective conductor located between the inner tube (10) and the outer tube (9) for connection with cable conductors within a closed end of the outer tube (10), characterized in that the inner tube (10) is formed for tight insertion into the outer tube (9) and has substantially rectangular slots (11) formed in its tube wall, each of said slots communicating with a comparatively narrow track (12) extending on the external side of said tube wall parallel to the tube axis from the slot to an orifice at one end of the inner tube (10), and that the terminals of the female part comprise contact flaps (13), each formed of a single flat rectangular planar surface having opposed edges abutting the inner wall of the outer tube each formed integrally with its respective conductor (14) for loose arrangement into its respective slot and the track (12) communicating therewith prior to the insertion of the inner tube (10) into the outer tube (9), the conductors being of such length as to, on the insertion of the inner tube (10) into the outer tube (9), be led through an aperture at one end of the outer tube (9), which aperture is closed by a cap (8) after connection of said respective conductors (14) with the cable conductors. 
     
     
       2. A female connector part for an electrical jack-type connector, mainly for low voltage purposes, for receiving in matching relationship a rod-shaped male connector part (1) having terminals in the form of conducting, axially displaced contact rings (2), said female connector part (7) having axially and peripherally displaced inner terminals to form contact with the contact rings (2) of the male part and comprising an outer tube (9) and an inner tube (10) fitted therein, which is formed with slots for the arrangement of the terminals of the female part (7), each being in connection with a respective conductor located between the inner tube (10) and the outer tube (9) for connection with cable conductors within a closed end of the outer tube (10), characterized in that the inner tube (10) is formed for tight insertion into the outer tube (9) and has substantially rectangular slots (11) formed in its tube wall, each of said slots communicating with a comparatively narrow track (12) extending on the external side of said tube wall parallel to the tube axis from the slot to an orifice at one end of the inner tube (10), andd that the terminals of the female part comprise contact flaps (13), each formed of a single flat rectangular planar surface having opposed edges abutting the inner wall of the outer tube, each formed integrally with its respective conductor (14) loose arrangement into its respective slot and the track (12) communicating therewith prior to the insertion of the inner tube (10) into the outer tube (9), the conductors being of such length as to, on the insertion of the inner tube (10) into the outer tube (9), be led through an aperture at one end of the outer tube (9), which aperture is closed by a cap (8) after connection of said respective conductors (14) with the cable conductors. 
     
     
       3. The female connector part of claim 2 wherein said contact flaps (13) extend as chords of the inner wall of said outer tube (9) with opposed edges of flaps (13) pressed by the inner wall of outer tube (9).
